A classic sign of measles is:
a. Kaposi sarcoma
b. Stiff neck
c. Koplik spots
d. Bull's-eye rash
Rubeola is transmitted person to person principally by
droplets
airborne
contact
vector
The nurse called the IP informing that Susceptible patients who have been exposed to an individual with measles (contagious) asking how long should they be placed in airborne isolation,the IP should advise her
from the onset of symptoms until 4 days after the onset of the rash
from (9-21) day after exposure
until 10 days after the onset of the rash
from (9-26) day after exposure
PVB19 is transmitted Through respiratory secretions and droplets of saliva so in children who developed the slapped cheek rash appears the IP in his facility should recommend
Droplet precautions
airborne isolatin
no action needed
contact precautions
Rickettsia typhi , transmitted to humans by
contact
droplet
vector
airborne
classic sign of rabies in humans
Headache, and weakness
Hydrophobia
Koplic spot
rash

A paramedic has been exposed to a patient's blood. The patient is Hepatitis B e Antigen (HBeAg) positive and the paramedic is Anti-HBc and Anti-HBs positive. What is the risk of the paramedic
acquiring Hepatitis B infection from the source patient?
a. There is no risk of infection for the paramed c because he was previously infected and is now immune
b. There is no risk of infection for the paramedic because the patient is not infected
c. There is no risk of infection for the paramedic because he is immune due to vaccination
d. There is a high risk of infection for the paramedic
38-A patient infected with HIV has cavitary lesions on a chest x-ray and is placed in airborne precautions. Which of the following is considered the most likely diagnosis?
(A) Pneumocystis carinii pneumonia
(B) M. avium complex infection
(C) M. tuberculosis infection
(D) histoplasmosis pneumonia
HDV Depends on simultaneous infection with

While making rounds on a nursing unit, the IP encounters a nurse
who has just incurred a needlestick after giving an injection to a patient. The nurse tells the IP that the patient’s recent laboratory
results indicate that he has Hepatitis B, and the nurse has not
completed her Hepatitis B vaccination series. She requests the
IP’s advice. In reviewing the patient’s record, the IP finds that the
patient’s antibody to Hepatitis B is positive and his Hepatitis
B
surface antigen (HBsAg) is negative. The IP’s explanation of the
patient’s laboratory results indicates which of the following?
a. The patient is in the early incubation period of the disease
and has a low probability of transmitting Hepatitis B;
the nurse should report to Occupational Health
b. The patient had Hepatitis B in the past and does not have
active disease now; the nurse should complete her Hepatitis B series as scheduled, but no additional treatment is needed
c. The results indicate a possible error in the results and
another blood sample should be submitted
d. The patient does have Hepatitis B but the disease is
resolving; the nurse should report to Occupational Health
During an inservice for new employees, the IP describes
how Hepatitis B and human immunodeficiency virus (HIV)
are transmitted. A major difference in the epidemiology
of the two diseases is:
a. Presence of the causative agent in body fluids
b. The ability of the diseases to be transmitted during
sexual intercourse
c. The risk of transmission through needlestick exposures
d. The potential for airborne transmission
Serologic testing of a patient for HIV infection reveals the ELISA result to be reactive, but the Western Blot result to be negative. The BEST explanation for these findings is related to
(A) laboratory error
(B) false-negative serology
(C) sensitivity and specificity
(D) a 10- to 12-week incubation period
A woman in active labor with confirmed influenza has been admitted to an acute care facility. Recommendations for preventing influenza transmission between hospitalized infected mothers and their infants include all of the following except:
a. The mother should be placed on Droplet precautions
b. The baby should stay in the same room as the mother
c. Keep the isolette at least 3 feet away from the mother when she is not interacting with the baby
d. The baby should receive formula during the 5-day period following the mother's symptom onset

Patients diagnosed by chlamydia trachomatis should be instructed to refer their sex partners for evaluation, testing, and treatment if they had sexual contact with the patient during

the first week preceding onset of the patient's symptoms
